Preventing Calf Pneumonia: A Welfare Priority

Evidence-based prevention guide for bovine calf pneumonia -- the leading cause of calf mortality in the UK.

Key Facts

Calf pneumonia causes more deaths and antibiotic use in the UK than any other cattle disease
Risk factors include inadequate colostrum, high stocking density, poor ventilation, and mixing of different age groups
Prevention requires a systems approach -- no single intervention is sufficient
Vaccination against key respiratory pathogens reduces disease severity and mortality significantly
Ventilation assessment and improvement is one of the highest-impact welfare interventions in calf housing
The pen microenvironment -- temperature, humidity, air speed -- must be monitored and managed
Social housing of calves in groups reduces stress and likely improves immune function
Early treatment within 24 hours of first clinical signs significantly reduces mortality and chronic lung damage

Welfare Significance

Calf pneumonia causes significant suffering and death in millions of calves globally. The disease is preventable -- farms with high pneumonia rates almost invariably have identifiable management risk factors that can be addressed. A systematic prevention approach targeting colostrum, housing, ventilation, and vaccination delivers measurable welfare improvements that are sustained across calf crops.

What You Can Do

Have calf housing ventilation assessed by a specialist vet or consultant
Ensure 100% of calves receive adequate colostrum within 4 hours of birth
Implement a vaccination programme targeting the most common local respiratory pathogens
Train all staff to recognise and score early respiratory signs -- prompt treatment saves lives
